I never understand this argument. If feels like saying there is no reason to wear just a helmet in outer space because you'll die without a space suit anyway. Yes, there are other methods of fingerprinting that can track your with varying degrees of accuracy that you should be aware of. But IP still remains a highly effective one. And just like the space helmet, it isn't an either or. You'll have to wear both the suit and the helmet.
